Most of the time it succeeds. However, the test case for BUG196361 revealed occasional failures. If you configure an epair interface (both sides) immediately after creating it with "ifconfig epair create", sometimes the interface will get configured but not routes will be added.=20 Workarounds are: 1) Add a 1 second sleep between "ifconfig epair create" and statically configuring the a half of the epair. It is not sufficient to add the sleep between statically configuring the a half and using SLAAC to configure the B half. 2) Add a longish (precise time unknown, but > 5 seconds) sleep between destroying an epair interface and creating a new one. This bug has not been observed the first time that an epair is created. The test case, currently disabled, is sys/netinet/fibs_test:slaac_on_nondefault_fib6 --=20 You are receiving this mail because: You are the assignee for the bug.=
